Glove80 FW can be compiled directly from the MoErgo's online layout editor: my.glove80.com.

My most recent layout can be seen here: https://my.glove80.com/#/layout/user/e00fadad-ac46-4657-b3bc-47b5a41308cf

I occasionaly make a backup of the ZMK keymap (see zmk/glove80.keymap) to my dotfiles repo, in case I lose access to the layout editor in the future.

1. Hit Save and Build firmware. A file with .uf2 will be downloaded.
2. Plug first right half via USB-C. Hit magic + '. Upload the FW to the bootloader disk. It will automatically eject.
3. Plug left half via USB-C. Hit magic + ctrl. Upload the FW to the bootloader disk. It will automatically eject.
4. Done.
